Abstract

fetched live from OpenAlex

This paper examines techniques that have been used to estimate potential output and finds them wanting. We suggest a simple multivariate-filtering technique that is a generalization of the Hodrick-Prescott univariate filter. In univariate filters, only information about a variable itself is used in eliminating noise in order to obtain an estimate of the underlying trend. We suggest a generalization, wherein other information is used to sharpen the identification of potential output. For example, we note that, if movements in potential output have a different effect on inflation than do cyclical movements in output, then information on inflation may be useful in identifying potential output. The prospects for improving measures of potential output by using this and other information in the multivariate filter are demonstrated through Monte Carlo experiments. Evidence is also presented contrasting the results of using the multivariate filter on the historical Canadian data with the results from the Hodrick-Prescott filter and other, more traditional methods of estimating potential output. We argue that the multivariate filter has advantages over quasi-structural models of potential output because it can exploit general information from economic theory about what information might be useful, without imposing restrictions from imperfect representations of the true structure.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
